I think OP just activated the WP-Minify plugin, unticked the boxes, and re-enabled the settings one at a time until they found the setting that was causing the site to load funny (if I remember correctly, the CSS minification setting was the culprit back when I used that plugin)

i did that too, but not worked for me, i use two separate plugin minify-js, and minify-css.
and test them one by one,
i have to remove minify css , but i am using minify js, that give me a little boost in my site, may be i am using gzip and cloudflare , so that may not be supported, i have tried around 10 of other , but every time same result,
now what ever i do more, it bring a drop in my score, so i guess i am done with it, any way, thanks for your responce
